I USE THIS CHARGER TO CHARGE BATTERIES FOR MY BABY BOY'S ELECTRONICS. THIS CHARGER WAS THE BEST BUY I MADE THIS CHRISTMAS. SIMPLY INVALUABLE. THE ONLY THING THAT I DON'T LIKE ABOUT IT IS THE FACT THAT IT DOES NOT HOLD MORE BATTERIES. NOT TYPES OR SIZES OF BATTERIES. JUST A LARGER QUANTITY OF BATTERIES. OTHERWISE, IRREPLACEABLE.
